6. 6•2-1 = 12-1 = 11
9+2 = 11 11 = 1

7. 9•[8-2-3-(9-8)] 9-8 = 1
8-2-3 = 3 • 9 = 27+1 = 28

8. [7•3-(6+9)]/2= 6+9= 15
7•3 = 21 /2 = 10.5

9. 2•10/5+(7+5)/2= 7+5=12
2•10 = 20/2 = 10+12 = 22

10. 2•6-9-[5-(9-7)] 9-7 = 2
5-2 = 3
2•6= 12-9+3 = 3+3=6

11. 10+10/5-8 = 10/5 = 2
10-8+2= 2+2=4

12. [2-(10-8)]•6+3•5 = 10-8=2
2-2= 0 • 6 = 0+3•5 =15

13. 8/2/(6-4) = 6-4 = 2
8/2/2 = 4/2=2

14. 6[5+(14-8)/3] = 14-8=6 = 5+6/3= 2+5= 7•6 = 42

make sure you always use PEMDAS! those brackets are important too. once you do the problem inside the parentheses you go straight to the problem inside the bracket then move further on. please make brainliest :)!!

2.the solution set of x +y =5 and x-y =3
Nataliya [291]

Answer:

Check the solution below

Step-by-step explanation:

2) Given the equation

x +y =5... 1 and

x-y =3 ... 2

Add both equations

x+x = 5+3

2x = 8

x = 8/2

x = 4

Substitute x = 4 into 1:

From 1: x+y = 5

4+y= 5

y = 5-4

y = 1

3) Given

x+3y =15 ... 1

2x+7y=19 .... 2

From 2: x = 15-3y

Substitute into 2

2(15-3y)+7y = 19

30-6y+7y = 19

30+y = 19

y = 19-30

y = -11

Substitute y=-11 into x = 15-3y

x =15-3(-11)

x = 15+33

x = 48

The solution set is (48, -11)

4) given

x/2 +y/3 =0 and x+2y=1

From 1

(3x+2y)/6 = 0

3x+2y = 0.. 3

x+2y= 1... 4

From 4: x = 1-2y

Substutute

3(1-2y) +2y = 0

3-6y+2y = 0

3 -4y = 0

4y = 3

y = 3/4

Since x = 1-2y

x = 1-2(3/4)

x = 1-3/2

x= -1/2

The solution set is (-1/2, 3/4)

5) Given

5.x=1/2 and y =x +1 then solution is

We already know the vkue of x

Get y

y= x+1

y = 1/2 + 1

y = 3/2

Hence the solution set is (1/2, 3/2)

6) Given

3x +y =5 and x -3y =5

From 3; x = 5+3y

Substitute into 1;

3(5+3y)+y = 5

15+9y+y = 5

10y = 5-15

10y =-10

y = -1

Get x;

x = 5+3y

x = 5+3(-1)

x = 5-3

x = 2

Hence two solution set is (2,-1)

A fraction reduces to 36. If its denominator is 6x5, what is its numerator?
olchik [2.2K]
If you would like to find the numerator of a fraction, you can do this using the following steps:

denominator ... 6 * 5 = 30
numerator ... x = ?

36 = numerator / denominator
36 = x / 30
x = 36 * 30
x = 1080

The correct result would be 1080.
